With an almost identical logo to the one used by the MBTA in Boston, the city of Pittsburgh calls its light-rail system "The T" as well. It consists of less than a dozen stops, with only a few lines. At $1.75 for a fare, it's also fairly expensive (although CMU and Pitt students can ride for free with their student ID's). It is managed by PATransit, which is best known for its bus system.

Student: How do I get to Station Square?
Me: Take any 61 or 67 bus downtown. Get off at Market Square, walk to the T station, and take the T to Station Square.
Student: OK, so the 61 or 67... and then the what?
Me: The T. Any T line will get you to Station Square.
Student: What's the 'T'?
Me: It's a light-rail line.
Student: A what?
Me: A light-rail. You know, like a train? Like a subway, except that most of it is above ground.
Student: Really?
Me:(starting to get angry) Yes, really. It really exists. You can ride for free using your student ID, just like a bus.
Student: Are you serious?
